Trump just is his own worst enemy. And he has never apologized for the shutdown, which destroyed hundreds of thousands of American lives.
He was tricked into it by Fauci and Birx, but he didn’t have the guts to stop it and he has never apologized for his error.
Also, he was a big vax proponent and did nothing to protect people who didn’t want to be vaxed.
Finally, he attacked the governors who resisted the shut-down: Kemp (GA) and Abbott (TX) first, and then DeSantis (FL), who initially abided by Trump’s orders but then realized that this was suicidal for his state.
De Santis was heavily opposed by RINOs such as the Mayor of Jacksonville, the Dems in general, the teachers’ union, the police unions, and the medical establishment, so he really had to fight for this, and Trump’s attacks didn’t help.
I’d be okay with anybody who was wrong if they’d say they were wrong and apologize, but none of them (including Trump) will ever do that.
